60 meter pre-cut hank, 12 mm Single Rope Access (SRA) line made by Donaghys. Setting an access line is considered 'Best Practice' in tree work but finding the right line for the job has presented a challenge. SRA from Donaghy is made specifically for this purpose - its unique construction makes SRA ideal for use with toothed cam mechanical ascenders and SRT mechanical devices. SRA is a little too static for DbRT so be careful where you deploy this line.
